Dude, Space Marines are awesome. They might not be as manly as the Guard, but they're by far one of the most awesome armies in 40K.

No, they are not. Space Marines are shitty as fuck. Because they are so overpowered, everyone plays them. I went to a GW tourney, and 80 out of the 100 people there played space marines.

Precisely, meaning their not shitty. I to play Space Marines and my nemesis is Orks. Space Marines are easy to beat if you know how to. I also have an army of Tyranids and have played with Tau and Necrons, all against SMs.
